- Sole architect/developer on BaristaCore, a serverless application platform.
Detailed Description
- Developed BaristaCore - an open-source cross-platform 'serverless' framework written in .Net Core/WebAPI using the ChakraCore engine as a embedded JS runtime.
Barista comes with Barista-Fiddle, an integrated development environment that provides autocomplete and syntax checking of Barista scripts. Fiddle takes advantage of React, the Monaco editor, Flow and WebPack.
Barista utilized AWS hosted Microservices using API Gateway, S3, CloudFront and .Net Core-based AWS Lambda functions in conjunction with Cognito for user authentication. - Developed CruiseFin - a BI application that gathers information about cruise vacation pricing and aggregates the data in the form of PowerBI reports.
To crawl pricing data, ECS compute resources running Chrome instances on Linux based containers that collected content initiated though messages placed on a SQS queue.
The activities execute a a DotNet Core layer (similar to puppeteer) to automate the chrome instances retrieve cruise pricing data and turn it into structured data.
Finally this this content is fed into Azure Data Lake and allows trends to be identified via custom developed PowerBI dashboards.
